In recent researches, vendor managed inventory (VMI) policy is rarely considered for deteriorating items.   This study considered the supply chain partner’s collaboration via a VMI system and provided an EOQ model for a two-level supply chain (single supplier - single retailer) to examine the inventory management proceedings for VMI and non-VMI supply chains. By a new approach in modeling, the ...

The aim of this paper is to propose tools to adapt and parameterize the Material Requirement Planning (MRP) method under lead time uncertainty. We study multi-level assembly systems with one type of finished products and several types of components. We consider that each component has a fixed unit inventory cost and the finished product has a backlogging cost per unit of time. The lead times of...

In today’s digital age, industrial methods are shifting away from humans and toward machines. We choose automated systems for various jobs related to production systems, such as screening, manufacturing. A smart manufacturing system is one in which machines take the place of humans. Under influence inflation, this study proposes a production-inventory model with partial backlogging, an imperfec...

This study examines the effect of monetary inflation for a two-warehouse single-product inventory system, in which items are stored limited capacity Own Warehouse (OW) and an unlimited Rental (RW). Demand item is considered stock dependent. Items may deteriorate at different constant rate both warehouses. Shortages allowed stock-out period partially backlogged satisfied next replenishment point...

In this paper, we considered a deterministic inventory model with time-dependent demand and time-varying holding cost where deterioration is time proportional. The model considered here allows for shortages, and the demand is partially backlogged. The model is solved analytically by minimizing the total inventory cost. The result is illustrated with numerical example for the model. The model ca...
